Yehuda Ben-Zion

Yehuda Ben-Zion is a Professor of Earth Sciences at the University of Southern California (USC), affiliated with the Dornsife College of Letters, Arts and Sciences. He serves as Director of the Statewide California Earthquake Center (SCEC). His expertise lies in geophysics and seismology, with a focus on earthquake mechanics, fault dynamics, and seismic hazard assessment. He holds a Ph.D. in Geophysics and Seismology from USC (1990) and a B.S. in Geology and Physics from The Hebrew University of Jerusalem (1982).

Research interests include physics of earthquakes and faults, high-resolution fault zone imaging, earthquake source properties, and dynamic rupture processes. Recent work emphasizes multi-scale modeling of rupture zones, seismic velocity monitoring using anthropogenic signals (e.g., train tremors), and probabilistic seismic hazard analysis frameworks like CyberShake. He leads projects such as Quakeworx, an open-source earthquake simulation platform, and investigates fault zone architecture in regions like the San Andreas, San Jacinto, and Marmara faults.

His studies address critical questions about large earthquake mechanisms, ground motion prediction, and the interplay between tectonic stress and seismicity patterns. He has pioneered the use of dense seismic arrays and machine learning to analyze seismic data, advancing understanding of fault zone processes and their implications for hazard mitigation.
